INFLUENCE OF CHLORELLA AND SCENEDESMUS ALGAL EXTRACTS ON THE ECONOMIC TRAITS OF SILKWORM, BOMBYX MORI L.

Silkworm Bombyx mori L. feeds on the leaves of mulberry tree which is only the host plant for silkworm. The improvement of larval feeding is enrichment of mulberry leaves with supplementary nutrients. The present study has been aimed at investigating various economic traits of the silkworm cocoon, when fed on mulberry leaves fortified with Chlorella and Scenedesmus algal extracts. The algal extracts was diluted by different concentrations 2%, 4% , 6% and 8% fed once a day from 3rd instar onwards, respectively. In was significantly increased the larvae, economic traits like cocoon weight, shell weight, pupa weight, shell percentage, filament length, fibroin, sericin and denier of silk filament.
